jumping beans & .tape. from la bisogno on Vimeo.

What might a jar full of Mexican jumping beans sound like if composing their own ambient music? Scott Worley points us to a musical experiment by his labelmate Daniel Romero aka .tape, on netlabel yo.yo.pang!.
.tape programmed a sound environment in the free multimedia patching environment Pd (Pure Data). Contact microphones listen for the beans to jump, then use Pd’s onset detection (an analysis for transients) to trigger the sounds. Daniel reports the technique is “easy, but wholly effective.”

I’ll say – the music winds up being quite lovely, and rather than having a boring software-based random event generator, there’s something mesmerizing about watching the beans. You can download a free MP3/OGG file of the track, as well (and it sounds as though more projects may be coming):

Descripción original en Español:

empezamos esta serie con la picante unión entre el músico Daniel Romero (aka .tape. ) y Pancho, Emiliano y Marcos, tres frijoles saltarines mexicanos

Sonidos y programación por .tape. secuenciación en directo por los 3 frijoles saltarines mexicanos micrófono de contacto + un “onset detection” en pd para disparar los sonidos. fácil pero rotundamente efectivo.

In other Pd news, the creators of the RjDj interactive/generative iPhone music app, which employs Pd patches, will be holding another sprint. This one will be located in London October 2-4.

    Hello. I´m a Mexican freelance reporter working on a story about the Mexican Jumping Beans. I was looking for sound on the web and found your very enchanting experiment. Could you share the audio with me? I´m making a radio documentary piece. I still don´t know where it will air, but I would tell you when this happened. Greetings from Mexico City

  • Living proof that the minimum required intelligence to be a musician is met by a larvae. Hurray, I cannot be declined musician status anymore! ^_^

    Very nice generation though.
